Avengers: Doomsday Trailer Expected This December
The first footage of Avengers: Doomsday is anticipated to debut in theaters this December, accompanying another major Disney release. Although the film itself will hit theaters in December 2026, fans might not have to wait long for a glimpse of the movie.
Trailer Attached to Avatar: Fire and Ash
According to multiple sources reported by Collider, the initial trailer for the MCU's next major team-up will be shown alongside the latest installment of Disney's hit franchise, Avatar: Fire and Ash. This plan may still change, but if it stays on track, audiences will catch their first look at Robert Downey Jr.'s titanium-masked supervillain on December 19.
Release Timing Connection
This timing aligns well with the release of James Cameron's third Pandora adventure, set for nearly exactly one year prior to Doomsday, which premieres on December 18, 2026.
Years of Builds and Surprises
This year, with the premieres of Thunderbolts and The Fantastic Four: First Steps, Marvel has laid much of the groundwork leading up to Doomsday. Earlier in 2025, excitement surged when Marvel revealed set chairs for the cast, hinting at the return of several characters from the 20th Century Fox X-Men universe.
Secrecy Around the Project
Despite the buildup, details about the crossover remain closely guarded, even from the actors themselves. Alan Cumming, reprising his role as Nightcrawler, shared that filming started before the final script was completed.
